Detailed Description

The utility model will be further described with reference to the drawings and embodiments.

First embodiment:

referring to fig. 1-4 in combination, in an embodiment of the present utility model, a die for automotive stampings includes: the punching machine 100 and the main body mechanism 200, the main body mechanism 200 is installed at the lower end of the punching machine 100, the main body mechanism 200 comprises an outer ring 203, a pressing strip 204 extending towards the inner diameter direction is arranged at the upper end of the outer ring 203, when the punching machine is used, firstly, a round steel sheet for punching parts is placed at the upper end of a second die 202, then under the action of an external device, the punching machine 100 translates downwards until the pressing strip 204 at the upper end of the outer ring 203 presses the round steel sheet on the second die 202, the round steel sheet is fixed, and finally, the punching machine 100 is started to punch and form the round steel sheet.

By arranging the outer ring 203 and the pressing bar 204, the round steel sheet can be temporarily fixed on the second die 202 in the downward translation process of the punching machine 100, compared with the existing mode of directly punching the round steel sheet by using the punching machine 100, the method reduces the interference to the prototype steel sheet in the contact process of the first die 201 and the round steel sheet and the vibration process generated by the action of the punching machine 100, so that the position of the prototype steel sheet changes, the punching position of the round steel sheet is inaccurate, and the qualification rate of produced parts is low.
